Window Caulking and Draft Sealing in Alhambra, CA

Short answer: Cracked caulk is removed and windows get sealed around the frame.

Cold air near the window and a damp sill after a storm usually come from the same gap. We cut out the dried caulk, reseal the frame to the wall, patch loose glazing, and renew the seals so the window shuts tight.

What’s included

  • Exterior caulk between frame and stucco or siding replaced
  • Interior trim gaps sealed and touched up
  • Loose glazing putty on wood and steel windows patched

  • Sash seals added to wood double-hung windows
  • Gaps around wall AC units and pipes sealed

What we don’t do

  • New openings cut into a wall for a door or window.
  • Glass cutting and glazing; we send that to a glass shop.
  • Garage door openers, springs and cables.

In Alhambra homes

About 77 percent of Alhambra’s homes were built before 1980, according to a city housing report, and many keep their original wood or steel windows. Their caulk and putty have dried and shrunk over the decades, which is where most drafts and rain leaks start.

Outside first

The exterior joint keeps rain out of the wall. We remove the old bead, clean the surfaces, use backer rod in wide gaps, and tool in fresh sealant.

Inside second

A thin bead where the trim meets the wall and frame stops air moving into the room.

Glazing on older windows

Loose putty lets the glass rattle and air through. We patch it so the sash seals again.

Sliders

Aluminum and vinyl sliders seal with pile strips. Flattened pile is replaced in the right height.

When it’s not caulk

Fogged glass, cracked frames or water inside the wall go to a window or stucco contractor.

In older Alhambra houses this job often turns up next to weatherstripping and door sweeps, window lock and crank repair, caulk and grout repair, window leak repair and blinds and curtain rod installation, so mention those when you text and we can price them together.
